Sound familiar?
The pain points no one warned you about.
Wrong COGS & Inventory Valuation
Your accountant expenses inventory when you buy it, not when it sells. This destroys your P&L accuracy — you don’t know real margins per SKU.
VAT Overpaid on FBA Fees
Storage fees, advertising spend, and certain fulfilment charges carry potentially reclaimable VAT on eligible FBA fees. Most accountants miss this entirely because they don’t understand FBA fee structures.
Returns & Reimbursement Chaos
Customer returns, lost inventory reimbursements, and damaged stock credits — your books never match Seller Central because nobody reconciles the settlement reports. Is this for you?

03 VAT Done Right Across Markets
UK, EU OSS, and IOSS handled together — no double-paying, no missed reclaims on storage and ad spend.
Questions? We’ve got answers
The most common questions.
We pull the full settlement report from Seller Central (or via A2X / Link My Books into Xero) and categorise every line: referral fees, FBA fulfilment, storage, PPC, refunds, reimbursements, and disbursements. Reconciling only the bank deposit is how generalists hide fees inside revenue and break your true margin. You see a real P&L by SKU, not a Frankenstein number.
Since Aug 2024 Amazon UK invoices most seller fees through Amazon EU S.a.r.l. UK Branch with UK VAT, which is reclaimable on your VAT return if you are VAT-registered. We audit the last 4 years of fee invoices, identify reclaimable VAT on storage, advertising and fulfilment, and submit the correction. Most FBA sellers we onboard recover £1,500-£6,000 in the first quarter.
Yes. We register and file UK VAT, EU OSS for B2C distance sales, and IOSS for sub-€150 imports, plus local VAT registrations wherever Amazon stores your stock (DE, FR, IT, ES, PL, CZ). We reconcile the VAT Transactions Report monthly so nothing falls between jurisdictions and you never double-pay.
If they expense inventory at purchase instead of at sale, miss reclaimable VAT on FBA fees, or hand you a single-line P&L, you are almost certainly overpaying tax and flying blind on margin. We handle the entire handover (HMRC re-authorisation, records transfer, Xero rebuild) in week one with zero effort from you, and most FBA clients recover our annual fee within the first VAT return.
Fixed monthly pricing from £99 (Essentials) up to £499 (Enterprise), covering bookkeeping, VAT, year-end accounts and unlimited email support — replies inside 72 hours, every message. Onboarding takes 5-10 working days from signed engagement letter, with a 30-day money-back guarantee and rolling monthly terms, so there is no long contract to escape if it isn't a fit.
